The role of acetylcholinesterase is to ________.Question 17Select one:a.destroy ACh a brief period after its release by the axonal endingsb.increase sarcolemmal permeability to Ca2+c.amplify or enhance the effect of Achd.act as a transmitting agente.stimulate the production of serotonin
Solution
The role of acetylcholinesterase is to:
a. destroy ACh a brief period after its release by the axonal endings
Acetylcholinesterase is an enzyme that breaks down acetylcholine, a neurotransmitter, in the synaptic cleft (the space between neurons) after it has been released from the axon endings. This process is crucial for the proper functioning of the nervous system because it ensures that acetylcholine does not continue to act on a neuron after it has already sent a signal. This prevents overstimulation of the neuron and allows for the transmission of new signals. Therefore, the correct answer is a. destroy ACh a brief period after its release by the axonal endings.
